Application June 24, 1955, Serial No. 517,674

7 Claims. (Cl. 189-72) This invention relates to window frames; and moreparticularly, to metal horizontal sliding window frames.

In recent years metal. horizontal sliding, windows have becomequitepopular. The prior art horizontal sliding windows, however, possess anumber of objectionable features which are overcome by the horizontalsliding window frame of the present invention.

The conventional frames consist of rear and forward frame members whichlap the stud, plaster and sheathing around the rough opening providedfor the window. The thickness of the stud, plaster and sheathing mayvary considerably; and, as noprovision is usually made for differencesin overall wall thickness the frame is not tight and rather large cracksmay be left between the rear frame member and the plaster.

A second objection is the fact that the window panels rattle and are notweather-tight within the panel-receiving channels of the forward framemember. This, of course, becomes quite annoying and also results indrafty rooms.

A further difficulty arises in that leakage often occurs betwen the rearand forward frame members as no provision is made to protect the seam.therebetween.

It is, therefore, the principal object of the present invention toprovide a metal horizontal sliding window frame which is provided withmeans for adjusting the frame to accommodate different wall thicknesses.

A second object of the invention is the provision. of a horizontalsliding window which is provided with an improved weather-strip whichprevents drafts and rattling of. the panels within the window frame.

A third object of the invention is the provision of means for protectingthe seam between the rear and forward frame members against leakage.

Other objects will be in part apparent and in part pointed outspecifically hereinafter in: connection. with the description of thedrawing which follows, and in which:

Figure 1 is a fragmentary rear. elevation showing the lower lefthandcorner of a metal horizontal sliding. window frame constructed inaccordance with the present invention; 7

Figure 2 is a section. taken along line 22 of Figure 1;

Figure 3 is a fragmentary perspective view of the adjustable framemember; and,

Figure 4 is a fragmentary perspectiveview of' the rear frame member.

In order to facilitate the description of the window frame of thepresent invention in connection with Figure 2 of the drawing, thefollowing designations will be used in the specification. and claims:the; left side of Figure 2 will be" the front or forward portionthereof; the right side the rear. or rearward portion; the bottom is theoutside or outer portion thereof; and, the top the inside or innerportion. Hence, an element extending from right to left would beforwardly extending, and one extending from left to right rear-- wardlyextending. in like manner, an element extend- 7, 2,826,282 Patented Mar.11,1958

ing from the upper. portion of the frame to the lower would extend'outwardly, and one extending from the lower to the upper portioninwardly.

Referring. now to the drawing, it will be seen that the metal horizontalsliding window of the present invention consists of four basic elements,namely: the panels 10, one of which is shown in Figure. 2; forward framemember 12, rear frame member 14; and, adjustfinished wall in theconventional manner as shown in Figure 2.

Referring in particular to Figure 2 of the drawing where the elements ofthe'window are shown in section, it will be seen that forward framemember 12 is provided with a web 24, a second flange 28 extendingoutwardly from the forward. portion thereof, and a third flange 26extending rearwardly from the first flange in spaced parallel relationto the web. If desired, the appearance of the forward frame member maybe enhanced by forming offset portion 30in the web 24, as shown. Anintegral fin 32 projects outwardly from the rear edge of.

the third flange 26' and provides means for attaching the forward framemember to the sheathing 22. The

integral fin isprovided with a plurality of openings 34* to receivenails 36. Exterior finished wall 38 covers the integral fin. Two panelreceiving channels 40 are formed in the exposed face of the web 24 byforward flange 42, middle flange 44 and rear flange 46. The forward,middle. and rear flanges are formed integral with the web in spacedparallel relation to one another and extend inwardly. Opposed grooves 48are formed in the opposed faces of rear flange 46 and middle flange 44;and, the opposed faces of middle flange 44 and forward flange 42 for thereception of spring weather-strips 50. The weather-strips are placed inthe opposed grooves 48, as shown, and engage frame 52 of panel 10 onboth the forward and rear faces thereof forming a double seal. Theweather-strips also prevent the panels from rattling. Second flange 54projects outwardly from the rear edge of web 24. The second flange 54 isprovided with a plurality of openings 56 to receive screws 58. A fourthflange 60 is formed integral with the forward frame member between rearflange 46 and second flange 54 and forms means for protecting the seam62 between second flange 54 of the forward frame member and connectingflange 64 of the rear frame member against leakage.

The details of construction of the rear frame member 14 will now bedescribed in connection with Figures 2 and 4 of the drawing. Rear framemember 14 comprises a plate 66 which overlies the exposed edges of stud18 and interior finished wall 26. The forward edge of plate 66 isprovided with an integral connecting flange '64 extending laterallytherefrom and adaptedto abut second flange 54 of the forward framemember 12-, as shown. Connecting flange 54 is provided with openings 68which register with corresponding openings 56 in the second flange 54.The screws 58 are used to attach the rear and forward frame memberstogether. Plate is provided with an integral intermediate flange 70which projects outwardly therefrom in the direction of'the stud; Channelflange 72 projects rearwardly from the intermediate flange in spacedparallel relation to the plate 66. Thus, a web receiving channel 74 isformed in the rear frame member along the rear edge thereof by theplate, intermediate flange and channel flange. Plate 66 is also providedwith two or more spaced ribs 76 which,

a? project into the web receiving channel 74. Locking rib 78 projectsfrom channel flange 72 into the web receiving channel 74 opposite spacedribs '76 of the plate.

In connection with Figures 2 and 3 of the drawing it will be seen thatthe adjustable feature of the horizontal sliding window frame of thepresent invention is accomplished by means of adjustable frame member16. The adjustable frame member consists of a serrated web 8% whichslides within web receiving channel 74 of the rear frame member betweenspaced ribs 76 and locking rib 78. Spaced ribs 76 prevent the serratedweb 50 from tilting within the web receiving channel. The outer face ofthe serrated web 80 which slides over the locking rib 78 is providedwith a plurality of longitudinally extend ing serrations 82 which act incombination with locking rib 78 of the rear frame member to prevent theadjustable frame member from being withdrawn from channel 74 once it hasbeen properly positioned therein. Trim flange 84 extends outwardly fromthe rear edge of the serrated web 8% along the interior finished wallsurface 20 and forms a decorative trim for the rear face of the frame.Wall engaging flange 86 extends forwardly from the trim flange to theinterior finished wall surface 2%.

Adjustable frame member 16 makes it possible to vary the distancebetween the forward edge of wall engaging flange 85 and integral fin 32to accommodate variations in wall thicknesses. It can easily be seenthat once the forward and rear frame members are in place, the adjustable frame member need only be inserted in the web receiving channel74 of the rear frame member and moved forwardly into the channel 74until the wall engaging flange comes into contact with the interiorfinished wall surface 26. Locking rib '78 will be engaged in theserrations $2 of the serrated web 86 to hold the adjustable frame memberin this position.

From the foregoing description of the drawing it will be seen that themany useful objects of the metal horizontal sliding window frame of thepresent invention have been achieved; and therefore, I claim:
